Proudly marching down the main street of Keene, New Hampshire, this band was probably one of several participating in the annual Independence Day parade in 1911. The gentlemen wear a fairly simple uniform with dark pants and a straight-cut coat with simple trim along the edges, and conductor-style billed caps.
Behind them on the left we can just see the over-decorated wide brimmed hat of a well dressed lady from that period, while to the right are several boys wearing knickerbockers — a baggy version of knee-breeches gathered just below the knee where they meet the long dark stockings. Some are wearing suit coats over those, and even those that aren’t seem to have long sleeves, even though it is July.
A couple men to the right have the flat-topped straw hats called boaters, with their broad contrasting dark grosgrain or silk hat bands.
Besides the ubiquitous American flags, several people have large dark umbrellas for shade from the bright sun, which is above, behind and to the left of the photographer.
